Subject: [PATCH v2 3/3] ARM: OMAP2+: AM33XX: Add tps65217 device tree data

Add device tree data for tps65217 regulator by adding all the consumers
necessary for AM335X-BeagleBone. The data will be map to a regulator
constraints which is required for regulator set_voltage and get_voltage
calls.

All tps65217 PMIC regulator constraints are placed in a seperate device
tree include file (tps65217.dtsi).

This patch is tested by adding the I2C slave address of TPS65217
pmic to am335x-bone.dts file (Not included in this, I2C slave
addition patch will be submitted to linux-omap, where am335x-bone.dts
binding file is available).
